DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a packaging bag with an outlet tube of the present invention will be described below with reference to the drawings. FIG.
Is composed of a bag main body A having an accommodation chamber 1 capable of accommodating an object to be accommodated, and an ejection pipe B having an ejection hole 11 capable of ejecting the object to be accommodated.

The bag body A is formed in a bag shape by heat-sealing the inner surfaces of a flexible packaging sheet 3 having a heat-fusible resin layer on the innermost surface by heat sealing. A gusset (bottom folded sheet) is formed in the part 4 and is formed to be self-supporting. The bag body A is divided into a hermetically sealed chamber 2 and the accommodation chamber 1 by a partition wall 5 formed by heat-sealing the inner surfaces of the stacked packaging sheets 3 to each other. The sealed chamber 2 is formed to protrude above the storage chamber 1 and to be eccentric to one side edge 6 side,
On the other side edge portion 7 side, a filling port 8 opened for filling an accommodation object such as a liquid into the accommodation chamber 1 is provided. A notch 9 for opening the sealed chamber 2 is formed on one side of the sealed chamber 2.

The injection pipe B is attached to the inner surface of the partition wall 5 of the bag body A, and the injection pipe B is attached to the mounting body 10 fixed to the partition wall 5 by heat fusion. A telescopic bellows portion 12 formed integrally with the mounting body portion 10 and housed in the sealed chamber 2; and a stopper formed integrally with the tip of the bellows portion 12 to close the pouring hole 11. The pouring tube B is formed integrally with a synthetic resin of a material that can be heat-fused to the inner surface of the packaging sheet 3, for example, a polyethylene or polypropylene resin.

The mounting body 10 is provided at the end 1 on the sealed chamber 2 side.
It is formed in a divergent shape extending from 0a toward the opening 10b on the accommodation room 1 side. Specifically, it is formed as a tapered tube in which the thickness of the tube is constant and the diameter of the pouring hole 11 gradually increases, and is formed to have substantially the same thickness as the bellows portion 12.

Below the opening 10b of the mounting body 10, the lower end of the partition 5 is opened from the left and right from the opening 10b.
A pair of left and right fall prevention portions 14 protruding toward the center of is formed. The fall prevention portions 14 and 14 are attached to the mounting trunk 10.
Is engaged with the opening 10b of the mounting body 10 in order to prevent the detachment of the mounting body 1 from the accommodation chamber 1 side.

Further, the plug 13 includes a flange portion 15 located at the end (upper end) of the pouring hole 11 and a flange portion 1.
5 and a projection 16 protruding upward from the plug 1.
3 between the flange 15 and the upper end of the bellows 12
A cylindrical portion 17 is formed. Also, the protrusion 16
After the cylindrical portion 17 is cut off to separate the plug 13 to open the pouring hole 11, as shown in FIG. 3, it is fitted into the formed spout 18 to form a resealable cylindrical shape. Be done.

Next, a method of using the packaging bag having the above configuration will be described. First, an accommodation object such as a liquid detergent is filled into the accommodation room 1 from the filling opening 8, and the filling opening 8 is heat-sealed to seal the accommodation room 1 for storage and transportation. At the time of transportation or the like, the mounting body 10, the bellows portion 12, and the plug 13 are integrally formed, and the pouring hole 11 is sealed by the plug 13, so that the liquid in the storage chamber 1 is There is no danger of leakage from the discharge pipe B to the outside (into the sealed chamber 2). In addition, since the bellows portion 12 and the plug 13 are housed in the sealed chamber 2 and are isolated from the outside, a small amount of liquid may enter the sealed chamber 2 from the heat seal portion of the mounting body 10 during transportation or the like. Even if it leaks out, there is no risk of leaking out of the packaging bag.

Then, as shown in FIG. 2, the sealing sheet 2 is opened by separating the packaging sheet 3 from the notch 9, and the cylindrical portion 17 is opened.
Is cut off, the plug 13 is cut off, the spout hole 11 is opened, the bellows portion 12 is extended, the spout port 18 is connected to another container, and the container in the storage chamber 1 is refilled with another container. .

In this refilling operation, since the bellows portion 12 which can be extended and contracted is provided, the operation can be easily performed by being connected to another container. Also, the mounting body 10
Are formed in a divergent shape, so that even if an upward force is applied to the mounting body 10 when the bellows portion 12 is pulled upward and extended, the pouring tube B is securely extended without falling out of the partition wall portion 5. Can be done.

Further, since the mounting body 10 is formed in a divergent shape and the opening 10b on the accommodation chamber 1 side is widened,
The liquid easily flows into the pouring hole 11, and can be smoothly refilled.

When the filled liquid remains in the storage chamber 1, as shown in FIG. 3, the projection 16 of the separated plug 13 is inserted and fitted into the opened spout 18 so as to be filled. The outlet 18 can be resealed, and the bellows 12 can be contracted and stored after resealing.

At the time of this contraction, a downward force acts on the mounting body 10, but the falling-off prevention portion 14 provided at the lower end of the partition wall 5 prevents the mounting body 10 from coming off to the accommodation room 1 side. Thus, the bellows portion 12 can be reliably contracted without the attachment body portion 10 falling into the storage chamber 1.

In the present embodiment, a projection 16 is formed on the plug 13 which closes and seals the ejection hole 11 so that the opened spout 18 can be resealed. It is also possible to make a resealable configuration by appropriately changing the design of such a shape. Further, if the pouring hole 11 is sealed without providing a resealable structure such as the protrusion 16, there is no possibility that the liquid leaks out of the pouring tube B.

Further, in the above-described embodiment, the mounting body 10 is formed as a tapered tube. However, as shown in FIG.
It may be formed in a divergent shape extending from the end 10a on the side toward the opening 10b on the accommodation chamber 1 side, and various shapes can be adopted as the divergent shape.

As described above, the shape and configuration of the pouring tube B and the material and the like are not particularly limited, but the elastic bellows portion 12 is formed integrally with the mounting body portion 10, By integrally molding the entire discharge tube B,
The manufacturing cost can be reduced as compared with the case where they are formed separately as in the related art, and there is an effect that the packaging bag with the spout tube can be manufactured at low cost. Further, according to the configuration in which the mounting body 10 is a tapered tube and the fall prevention portion 14 is provided as in the above embodiment, even if the mounting body 10 is not firmly fixed, the discharge pipe B comes off. Therefore, the pressing force at the time of fixing (such as heat fusion) may be small. Therefore,
Even if the injection tube B is formed to be thin, it does not deform due to the pressing force at the time of fixing, and the bellows portion 12 can be thinned and improved in elasticity. Has an advantage that it can be easily formed by integral formation.

In the above embodiment, the fall prevention unit 14 is used.
Is formed so that the lower end portion of the partition wall portion 5 protrudes and extends, but may be provided separately from the partition wall portion 5 without being formed integrally with the partition wall portion 5. If the inner surface of the packaging sheet 3 is formed by heat-sealing the inner surfaces of the packaging sheets 3 to prevent the mounting body 10 from being detached to the storage chamber 1 side, the configuration and the arrangement are within the scope of the present invention. Etc. can be appropriately changed in design. However, there is an advantage that by forming the partition unit 5 integrally with the partition unit 5, the fall prevention unit 14 can be formed at the same time when the partition unit 5 is formed by heat sealing.

The sealing chamber 2 may be formed at the center instead of being formed eccentrically on one side edge 6 side. The gusset of the lower edge 4 is not an essential requirement, and the sealing chamber 2 and the accommodation chamber 1 are formed by stacking a pair of rectangular wrapping sheets 3 and heat-sealing the peripheral edge and the partition wall 5. May be the bag body A
Is not limited.

The material of the packaging sheet 3 is not particularly limited. For example, a long-term use of food or the like (particularly, having fluidity) using an aluminum foil or a laminated film in which a film having a gas barrier property is laminated. It may be one that can be stored, or a tube-like film may be used.

[0032]

According to the packaging bag with the spouting tube according to the present invention, since the spouting tube is formed with an elastic bellows portion,
It is easy to refill the contents, and since the bellows part is formed integrally with the mounting body and stored in the sealed chamber, leakage of the contents to the outside of the bag body during transportation or the like is ensured. Can be prevented.

Further, since the bellows portion is formed integrally with the mounting body, the bellows portion is different from a conventional packaging bag in which the bellows portion is separate.
Packaging bags can be manufactured at low cost.

In particular, by forming the mounting body to have a divergent shape as described in claim 2, it is possible to improve the outflow property of the object to be accommodated in the accommodation room, and even if the bellows portion is extended. There is no danger that the outlet pipe will fall out of the partition.

In addition, as described in claim 3, by providing a drop-preventing portion on the side of the accommodation chamber side of the opening for preventing detachment of the mounting body from the accommodation chamber side, even if the bellows part is contracted, the injection bellows can be used. It is possible to reliably prevent the outlet pipe from falling into the storage chamber.

In particular, the mounting body is formed in a divergent shape as described in claim 2 and the fall prevention part is provided in claim 3, so that the mounting body can be extended and contracted in both operations of the bellows. This has the effect of reliably preventing separation from the partition.
